HEATER.

f ua citizen of the United States,v residing at Swissvale, in the county ofl Allegheny and State of ennsvlvania, have inventedcertain new andiuseful Improvements in Heaters, of which` the followin is a specification.

` My invention relates particularly to water heaters of the well known instantaneous type, and has forits objects to'provide an arraneement'of drip pan and casing whereby an a equate supply of air for the inner burners is secured; to provide an arrangement of heater casing and drip pan whereby a draft of air over thewater collected in the pan is secured; to provide a drip pan wherein the accumulated water is automatically disposed of at intervals in case the evaporation is not sufficient to securev this result; and, to provide a heater which u ill be less subject to injury in oaseof-an explosion. lOne form ofthe inventio-n is show n in the accompanying drawings, wherein;

Figure l-is a side view partly in elevation.

and partly in section, showing a water heater I with my invention applied thereto, and

n -Figure 2is a section on the line ille-'II of4 `Figure 1 looking down.'

n instantaneous heaters alarge amount of condensation occurs which condensation has heretofore been rovided for, and kept from the floor` beneat theheater by the use of a drip gpan mounted' in the`base off the heater'beneath the burners: No provision has heretoforel been made for the removal of the Water which collected, it being assumed that the heat from the burners should evaporate the water, and it would be carried from the heater inl the form of vapor. Experience has shown,` however, .that the water ordinarily collects more rapidly than it 'evaporates,

and as a result, water collects in the pan to a considerable depth and becomes foul, eventu ally rusting outthe bottom of the casing.vr

My invention is designed not only toobviate this diiiiculty by the provision of an automatic discharge of such pan, but to provide an arrangement of pan and casing for securing a better supply'of air for the inner burners of the heater, and wherein the constant 'draft .of air is secured over the surface of the water in the pan in order to hasten the evaporation.. My construction also lessens the da to the boiler in case of an exp osion.

Specification of Lettersilatent. Application led June 14, 1907. Serial No. 378,946.

Patented March 28, 1909.

\,Referring to the drawings, 1 is the heater casing which may be of any approved type and is supplied at its base with openings '2 for the passage of air to the burners, -3 is the boiler which maybe of any approved type4 are the burners, which are mounted in two rows on the annular base ring 5, 6 is the drip pan hingedat its rear edge on the 'pivot rod S, and 7 is an annular casting on which the casing 1 is mounted and which is provided with legs and downwardly projecting lugs 11 for engaging Vthe ends of the pivot `rod 8,

The pan Gis spaced away from the lower edge of the casting` 7 by means of the lugs 9, and

- comparatively long intervals, and the entire discharge of the water onto a floor provided with a drain is much less objectionable than a continuous 'gradual discharge which keeps the floor continually damp. n cases Where the floor is not provided with a drain the pan will `probably ordinarily be discharged manually from time to time into 'aA The upper edge ofthe pan 6 is receptacle. spaced away from the lower edge of the casting 7 by the lug 9 in order to provide an air space, so that a current of air from the bottom of the heater may be lsupplied to the burners and especially to the inner row thereof, which inner rowof burners have, in heaters heretofor constructed, been inadequately sup lied om side` openings in the casing SUC of course swing own, thereby.relieving` thek pressure in the boiler, -and .minimizing the as the openings 2, which arrangement has resulted in` an inner set of burners of low danger of a rupture'to thecasing .and other injuries. I The invention' is obviouslynot confined to the use of acoiled spring, as any suitable means for holding the panv yieldingly in its upper'position might` be substituted without departing froni'the invention; Such illustrated-its use, what I l and yielding .hold thi-condensation Jfrom the heater and 1,55.,
